Synchronizing keys after changing ECU/TCU/BCM

Modern vehicles use advanced security systems where the key must be electronically synchronized with control modules such as the ECU, BCM, or TCU. After replacing one of these modules the vehicle key may no longer be recognized by the immobilizer system, preventing the engine from starting. In these situations the keys must be reprogrammed and synchronized with the vehicle's electronic modules. At FIX SERVICE in New York we perform start system diagnostics, check the immobilizer system, and program or synchronize keys after ECU, BCM, or TCU replacement. Using professional diagnostic equipment we properly adapt the keys and restore normal operation of the vehicle security and starting system.
